纵观2001年全国各地中考试题,不难发现,有相当一部分试题都以坐标几何题作为压轴题.此类试题倍受命题者青睐.究其原因,它是代数与几何的综合题,构题者巧妙地将几何图形置于坐标系中,通过函数图象为纽带,将数与形有机结合,并往往以开放题的形式出现,是考查学生综合能力的好素材. Looking at the examination questions throughout the country in 2001, it is not difficult to find that there are quite a few questions that use coordinate geometry questions as the finale questions. Such questions are favored by propositions. The reason is that it is a comprehensive problem of algebra and geometry. Ingeniously placing geometric figures in the coordinate system and using the image of the function as a link, the organic combination of numbers and shapes, and often appearing in the form of open questions, is a good material for examining students’ comprehensive abilities.
